Description
FIELD OF INVENTION

The present invention relates generally to apparatus in the field of respiratory therapy. More particularly, the present invention relates to a double-body therapeutics face and tracheostomy mask which functions as both a mask for the nose and mouth, as well as a mask for communication with a tracheostomy tube of a patient.

BACKGROUND

Nebulizers which produce a fine spray or mist have long been used in the treatment of various ailments and in the administration of medication. Masks have been developed which are in fluid communication with nebulizers and which are worn by the patient to more efficiently deliver the spray or mist to the nose and/or mouth of the patient. U.S. Pat. No. 4,938,209 discloses such a nebulizing mask that is equipped for the nose and/or mouth of a patient.

Additionally, patients who suffer from an obstruction in the respiratory tract are often treated with surgery to create an opening in the neck through which to breathe. The result of the surgery is a stoma or breathing hole in which the patient is often intubated with a tracheostomy tube. Such patients often require the infusion of a gaseous medicament, such as oxygen, which is supplied into the tracheostomy tube. U.S. Pat. No. 5,749,360 discloses such a tracheostomy mask.

Each of the nebulizing masks currently existing in the prior art, however, deliver the spray or mist to either the nose and/or mouth, or to the trachea. Thus, a patient needing nose, mouth, and tracheostomy nebulizing must carry out the nebulizing exercise once for the nose and mouth by way of face mask, and then repeat the process for tracheostomy nebulizing by way of a separate tracheostomy mask. Nebulizing is often necessary five to fifteen times over a twenty-four hour period for twenty to thirty minutes each time to ensure that all three orifices are sufficiently nebulized. A need has therefore been felt for a double-bodied mask that allows for simultaneous nebulizing of all three orifices through a single communication incorporating the functions of two conventional masks, while allowing for increased convenience for the patient.

The present invention describes a double-body mask that provides the advantage of reducing patient nebulizing time by addressing both face and tracheostomy nebulizing simultaneously. The present invention describes an improved delivery system of the nebulizing fluid, which may enter the mouth, nose, and tracheostomy tube of a patient.

SUMMARY

Accordingly, it is an object of the present invention to provide a simultaneous nose, mouth, and tracheostomy mask.

One embodiment of the invention is a double-body face and tracheostomy nebulizing mask providing fluid communication with a nebulizing apparatus for delivery of nebulizing medicaments, mist, spray or gaseous therapeutics simultaneously to the nose, mouth and tracheostomy tube of a patient, which includes an upper-body defining a rearwardly opening cavity for receiving the face of a patient and a forwardly disposed opening for receiving from a nebulizing apparatus at least one of nebulizing medicaments, spray, mist, and gaseous therapeutics, a lower body having a rear portion which terminates in an opening defined by a perimeter for receiving the neck of a patient, and a forwardly disposed opening for receiving from a nebulizing apparatus at least one of nebulizing medicaments, spray, mist, and gaseous therapeutics, wherein the rear portion has an interior surface that is adapted for communication with the tracheostomy tube, and a delivery conduit having at least three end portions, wherein the first end portion is connected to the forwardly disposed opening of the upper body, the second end portion is connected to the forwardly disposed opening of the lower body, and the third end portion communicates with the nebulizing apparatus.

Another embodiment is a double-body face and tracheostomy nebulizing mask providing fluid communication with a nebulizing apparatus for delivery of nebulizing medicaments, mist, spray or gaseous therapeutics simultaneously to the nose, mouth and tracheostomy tube of a patient, which includes an upper-body defining a rearwardly opening cavity for receiving the face of a patient and a forwardly disposed opening for receiving from a nebulizing apparatus at least one of nebulizing medicaments, spray, mist, and gaseous therapeutics, a lower body having a rear portion which terminates in an opening defined by a perimeter for receiving the neck of a patient, and a forwardly disposed opening for receiving from a nebulizing apparatus at least one of nebulizing medicaments, spray, mist, and gaseous therapeutics, wherein the rear portion has an interior surface that is adapted for communication with the tracheostomy tube and an adjustable-length delivery conduit, wherein a first vertical portion is adjustable in length and is connected to the forwardly disposed opening of the upper body, wherein a second portion is connected to the forwardly disposed opening of the lower body, and wherein the first vertical portion delivery conduit communicates with the nebulizing apparatus.

A preferred embodiment of the present invention includes a moldable plastic double-body mask that is lightweight and sanitary. The mask functions as two conventional nebulizing masks, namely, a facemask and a tracheostomy mask, and serves as a means for delivering a gaseous medicament or a liquid, such as liquid medication, in the form of a fine spray or mist to the nose, mouth, and tracheostomy tube of the patient. The upper body of the mask is designed to be placed over the nose and mouth area of a patient's face, and the lower body of the mask is designed to be placed over the trachea area of the patient's neck and in communication with a tracheostomy tube.

Mask embodiments of the present invention provides several advantages, including an increase in patient comfort. This is, in part, because the mask may be changed or reconfigured while the mask is still in place on the patient. This capability allows for the simultaneous nebulizing of all three orifices of the patient or the nebulizing of the nose and mouth separately from the tracheostomy nebulizing, if so desired. Another advantage of the present invention is that the mask may be manufactured from readily available materials, utilizing common manufacturing technologies and techniques.

Another advantage of the present invention is that the size of the upper body portion and the lower body portion may be of any suitable size. For example, a small surgeon or painter-type design, which covers the mouth/nose area of a patient may be used for the upper body. A small surgeon-type mask may be used in that it causes less emotional stress to a patient as compared to a larger design which covers a substantial portion of the face. Such a design may be well-suited for any patient, especially a child patient. In accord, the lower body portion may be designed to be any suitable size which covers the trachea stoma. A smaller mask design which cups around the trachea stoma will increase concentration of the nebulizing medicants delivered to the trachea. In the present designs, the nebulizing apparatus may be easily removed or disconnected from the delivery conduit for cleaning, refill and reuse.

In the mask embodiment comprising the adjustable-length delivery conduit, the length of the connection between the upper body and the lower body is adjustable in vertical length to fit to any number of patients. In this manner, a face and tracheostomy mask may be used by a child patient having a small distance from the face to the trachea and an adult patient having a larger distance from the face to the trachea area. In this manner, a face and tracheostomy mask may be adjusted to account for differences in the distance between the face and the trachea area which may be seen across different ages and races of patients.

Another advantage of the adjustable delivery conduit is that there is less tubing to clean after use. In alternatively described masks, an additional tubing may connect the delivery conduit to the nebulizing apparatus. With the elimination of such additional tubing, the mask design is less cumbersome to a patient. Additionally, with the elimination of such additional tubing, there is less distance for the nebulized fluid to travel to reach the mouth/nose and trachea area. Therefore, the adjustable-length design allows for a greater concentration of medicants to reach the patient.

All publications mentioned herein are incorporated by reference. Nothing herein is to be construed as an admission that the invention is not entitled to antedate such disclosure by virtue of prior invention.

The present invention provides a double-body therapeutics face and tracheostomy mask, including an upper body and a lower body, which functions as both a mask for the nose and the mouth, as well as a mask for the trachea of the patient. The mask of the present invention serves as a means for delivering gaseous medicament or liquid, such as liquid medication, in the form of a fine spray or mist to the nose, mouth, and tracheostomy tube of the patient.

A double-body mask according to one embodiment of the present invention is illustrated in the side view in FIG. 1. The mask is preferably made of a soft, flexible, clear material. The upper body 1 of the mask of the present invention is flexible and has an interior surface 12 and an exterior surface 13 and is designed to be placed over the nose and mouth area of a patient's face. The upper body 1 of the mask is secured to the patient's face by way of an elastic strap 6 that goes around the back of the head. When applied to the patient, the interior surface 12 is in communication with the patient and the exterior surface 13 is in communication with the ambient atmosphere. The lower body 5 of the mask is flexible, is designed to be placed over the trachea area of the patient's neck and to communicate with the tracheostomy tube, and is secured by way of an elastic strap 7 that goes around the neck. The upper body 1 and the lower body 5 of the mask of the present invention are each formed in the shape of a substantially continuous, cup shaped wall. The elastic straps 6, 7 may be fixed to the upper body 1 and lower body 5 of the mask by any conventional means, such as threading the straps through parallel slots 15, 16. Alternatively, snaps, VELCRO, hook and loop fasteners, clips, or any other conventional means may be used. Once the upper body 1 of the mask is secure against the face of the patient, a clip 10, preferably made of aluminum, is placed on the nose area of the mask of the patient in order to provide a closer fit around the nose and cheek area.

The upper body 1 of the mask of the present invention is connected to the lower body 5 of the mask of the present invention by a delivery conduit 2, preferably any ‘T’ connector which is known in the art. One end of the T connector 2 is attached to the upper body 1 of the mask. A second end of the T connector 2 is attached to the lower body 5 of the mask. The third end of the T connector 2 is attached to one end of, preferably, a pliable hollow accordion tube 3. Alternatively, the third end of the T connector 2 may be attached to hollow smooth tubing or any other conventional hollow tube. The other end of the hollow accordion tube 3 is connected to a nebulizing apparatus 4, such as a nebulizing cup, which is designed to atomize a liquid 8, such as a liquid medication, to produce a fine spray or mist. Thus, a delivery conduit 2 defines a passageway there through for fluid communication between the nebulizing apparatus 4 and the patient for spray and mist to reach the face and the tracheostomy tube. The nebulizing apparatus 4 is connected to a nebulizing machine from which airflow meets the nebulizing medicaments 8 to produce mist or spray. The end of the T connector 2 that is attached to the lower body 5 of the mask also contains an opening 11, or vent, in order to help alleviate a build-up of condensation within the hollow accordion tube 3 and T connector 2.

The upper body 1 of the mask of the present invention defines a rearwardly opening cavity for receiving the face of the patient, and a forwardly disposed opening for receiving the T connector 2. The T connector 2 is positioned so that, when the mask is worn by the patient, it is located below the nose of the patient. The upper body 1 also includes two vent holes 9 in order to help prevent condensation from building up inside the mask.

The lower body 5 of the mask of the present invention is flexible and has an interior surface 12 and an exterior surface 13. The lower body 5 of the mask is formed in a continuous, cup shaped wall and includes a rear portion which terminates in an opening defined by a perimeter 14. The perimeter 14 is sized and shaped for sealable engagement against the neck, tracheostomy tube, and stoma hole of the patient. The cup-shaped wall 14 of the lower body of the mask extends away from the rear portion and terminates in a forward portion which is connected to the T connector 2. Preferably, the lower body 5 tapers throughout this extension. The interior surface 12 is in communication with a tracheostomy tube when the mask is engaged on the neck of the patient. The lower body 5 also includes a vent hole 11 in order to help prevent condensation from building up inside the mask.

In FIG. 2, the double-body mask having the T connector 2 of the present invention is illustrated according to a frontal view. This view illustrates that the double-body mask includes two flexible mask bodies 1, 5. Again, the upper body 1 of the mask of the present invention is connected to the lower body 5 of the mask of the present invention by any ‘T’ connector 2 which is known in the art. One end of the T connector 2 is attached to the upper body 1 of the mask. A second end of the T connector 2 is attached to the lower body 5 of the mask. The third end of the T connector 2 is attached to one end of, preferably, a pliable hollow accordion tube 3. The other end of the hollow tube 3 is connected to a nebulizing apparatus 4, such as a nebulizing cup, which is designed to atomize a liquid 8, such as a liquid medication, to produce a fine spray or mist. Thus, a delivery conduit 2 defines a passageway there through for fluid communication between the nebulizing apparatus 4 for spray and mist to reach the face and the tracheostomy tube. The nebulizing apparatus 4 is connected to a nebulizing machine from which airflow meets the nebulizing medicaments 8 to produce mist or spray. The end of the T connector 2 that is attached to the lower body 5 of the mask also contains an opening 11, or vent, in order to help alleviate a build-up of condensation within the hollow tube 3 and T connector 2.

In FIG. 3, a double-body mask comprising an adjustable-length delivery conduit according to another embodiment of the present invention is illustrated in a side view. The upper body 1 of the mask has an interior surface 12 and an exterior surface 13 and is designed to be placed over the nose and mouth area of a patient's face. This upper body 1 may be designed in the shape of a surgery mask or a painter's mask, which fits over the nose and mouth of a patient, but is relatively small and convenient to a patient. The lower body 5 of the mask of the present invention is flexible, is designed to be placed over the trachea area of the patient's neck and to communicate with the tracheostomy tube, and is secured by way of an elastic strap 7 that goes around the neck. The lower body 5 may be designed so as to encircle the trachea. A smaller mask cupping 5 around the trachea stoma increases the concentration of nebulizing medicants to the patient as compared to a larger, more cumbersome design. The upper body 1 and the lower body 5 of the mask of the present invention are each formed in the shape of a substantially continuous, cup shaped wall.

The upper body 1 of the mask of the present invention is connected to the lower body 5 of the mask of the present invention by a delivery conduit 3, preferably any adjustable length tubing, such as extension tubing, or telescoping tubing, which is known in the art. The adjustable-length delivery conduit 3 has a first vertical portion which is adjustable in length and is connected to the forwardly disposed opening of the upper body 1. A second portion of the delivery conduit 3 is connected to the forwardly disposed opening of the lower body 5. This second portion is preferably perpendicular to the vertical portion of the delivery conduit 3. The first vertical portion of the delivery conduit communicates with a nebulizing apparatus 4. The nebulizing apparatus 4, such as a nebulizing cup, is designed to atomize a liquid 8, such as a liquid medication, to produce a fine spray or mist. Thus, a delivery conduit 3 defines a passageway there through for fluid communication between the nebulizing apparatus 4 and the patient for spray and mist to reach the face and the tracheostomy tube. The nebulizing apparatus 4 is connected to a nebulizing machine from which airflow meets the nebulizing medicaments 8 to produce mist or spray. The end of the delivery conduit 3 may contain an opening 11, or vent, in order to help alleviate a build-up of condensation within the vertical portion of the delivery conduit 3.

The upper body 1 of the mask of the present invention defines a rearwardly opening cavity for receiving the face of the patient, and a forwardly disposed opening for receiving the delivery conduit 3. The upper body 1 also includes two vent holes 9 in order to help prevent condensation from building up inside the mask.

The lower body 5 of the mask of the present invention is flexible and has an interior surface 12 and an exterior surface 13. The lower body 5 of the mask is formed in a continuous, cup shaped wall and includes a rear portion which terminates in an opening defined by a perimeter 14.

In FIG. 4, the double-body mask comprising the adjustable-length delivery conduit 3 of the present invention is illustrated according to a frontal view. This view illustrates that the double-body mask includes two flexible mask bodies 1, 5. Again, the upper body 1 of the mask of the present invention is connected to the lower body 5 of the mask by an adjustable delivery conduit 3 which is an adjustable tubing material. One end of the delivery conduit 3 is attached to the upper body 1 of the mask. A second end of the delivery conduit 3 is attached to the lower body 5 of the mask. The vertical end of the delivery conduit 3 is connected to a nebulizing apparatus 4, such as a nebulizing cup, which is designed to atomize a liquid 8, such as a liquid medication, to produce a fine spray or mist. Thus, a delivery conduit 3 defines a passageway there through for fluid communication between the nebulizing apparatus 4 for spray and mist to reach the face and the tracheostomy tube. The nebulizing apparatus 4 is connected to a nebulizing machine from which airflow meets the nebulizing medicaments 8 to produce mist or spray.

The masks of the present invention allow for nebulizing medicants to enter the mouth, nose and trachea area of a patient. In several embodiments of the mask, an upper body may be a small surgeon-type mask, which fits over the nose and mouth of a patient. In the masks described herein, the nebulizing apparatus may be easily removed or disconnected from the delivery conduit for cleaning, refill and reuse. In the masks embodiments, the lower body portion which connects to the trachea may be designed so as to allow a concentration of nebulizing mendicants to reach the trachea.

In an embodiment of the double-body mask, an adjustable-length delivery conduit allows for the mask to be worn by any sized patient. The use of the adjustable delivery conduit allows for less connective tubing to be used with the double-body mask. Less tubing allows for less cleaning, and less inconvenience for the patient. The adjustable delivery conduit also allows for a greater concentration of medicants to reach the mouth, nose, and trachea of the patient. In one design, the nebulizing container is built into the vertical tube that runs from the face to the trachea area. This allows for less condensation throughout the tubing. With less tubing, there is a smaller change for germs, contamination or bacteria to grow within the device.

Some of the preferred embodiments have been set forth in this disclosure for the purpose of illustration only. However, the foregoing description should not be deemed to be a limitation on the scope of the invention. Accordingly, various modifications, adaptations, and alternatives may occur to one skilled in the art without departing from the spirit and scope of the claimed inventive concept.
